Seven months of heat, and nights near freezing

Roswell needs a furnace from October through April. That is seven months of the year the burner is doing real work, not just a few cold snaps. Winter nights average 27°F, so a new furnace has to hold steady through a long stretch of real cold, night after night.

More than half of homes here heat with electricity, and the power does not always stay on. Chaves County has seen 11 winter storms and 108 damaging wind events over the past ten years, and 13% of New Mexico households lost power for 24 hours or more in 2024. That is worth factoring into how a new furnace gets chosen and installed. Any non-weatherized gas furnace built since November 2015 has to hit 80 percent AFUE at minimum, so that is the floor to compare against, not the goal.

New Mexico requires HVAC contractors to hold a state license.

The Construction Industries Division tests and licenses HVAC contractors across the state, and the license belongs to the contractor rather than to any single job. That means the person installing a furnace in Chaves County has already had to show the state they know the work, and the state keeps a record of who they are.

For a furnace installation, that license is what stands behind the work itself, but it is not the only check on the job. Most cities and counties in New Mexico also require a permit for a furnace replacement, with an inspection once the work is finished. That inspection is where a bad gas connection or a venting mistake gets caught before it becomes dangerous.

What size furnace does my house need?
The right size comes from a load calculation, not the square footage of your house alone. A contractor works through your insulation, window count, ceiling height, and layout to figure out how much heat the house actually loses on a cold night. Guessing high seems safe but it isn't. An oversized furnace cycles on and off too fast, which wears out parts sooner and leaves rooms feeling uneven. With winter lows here averaging 27°F and heat needed October through April, getting this number right matters more than in a milder climate, since the furnace runs hard for months, not just on the coldest days of the year.
How do I know it's time to replace my furnace?
Watch for repairs that keep coming back, heat that feels weaker than it used to, or rooms that heat unevenly. If a technician has been out more than once this season for the same kind of problem, that's usually the furnace telling you it's done. Age matters too. A furnace installed when your house was built has likely put in seven months of work every year since, October through April here, and that adds up over time. A furnace that runs longer than it used to just to reach the same temperature is losing ground, even if it hasn't broken down yet.
Is a high-efficiency furnace worth it?
It depends on how much you heat and what furnace you have now. Every non-weatherized gas furnace made since November 2015 has to hit at least 80 percent AFUE, so even a standard new furnace wastes less fuel than an older one might. Whether it's worth paying more for a higher-efficiency model matters more in a place where the furnace runs October through April, seven months a year, than somewhere with a short winter. A contractor can walk through the actual models and what each one means for your house, since the right choice depends on your ductwork and how the house holds heat.
